Abstract: A method for operating a multi-beam particle microscope which operates using a plurality of individual charged particle beams, wherein the method includes the following steps: measuring the beam current; determining a deviation of the measured beam current from a nominal beam current; decomposing the determined deviation into a drift component and into a high-frequency component; and controlling the high-frequency component of the beam current via a first closed-loop beam current control mechanism and/or compensating an effect of the high-frequency component on a recording quality of the multi-beam particle microscope using different mechanism than a closed-loop beam current control mechanism. An electrostatic control lens arranged in the beam generating system between extractor and anode can be used as first closed-loop beam current control mechanism. Adapting an extractor voltage of the beam generating system can be avoided.

Abstract: The present disclosure provides more efficient techniques for removing a host from a multi-host database system. An instruction to remove a host system may be received. In response, a determination of whether the first host system does or does not store any source tables is made based on a host-type identifier for the host system. This determination may not require obtaining landscape information for each of the hosts in the database system. If the host system stores replica tables and does not store source tables, those replica tables may be dropped based on the determination that the first host system does not store any source tables. As such, in cases where table redistribution is not needed the landscape information is not obtained, thereby making the host removal process more efficient.

Abstract: A disc brake for utility vehicles includes a brake disc, a first brake lining on a first side of the brake disc and a second brake lining on a second side of the brake disc opposite the first side. A spreading device is also provided which generates a force that moves the first and the second brake lining away from one another.

Abstract: The invention relates to a book production line and a method for producing individual books as well as very short and short runs of books. The book production line comprises a feed device and a following transport section for book covers, a feed device and a following transport and processing section with a rounding and pressing machine, an adhesive-backing apparatus for book blocks, and a casing-in machine. The rounding and pressing machine forms an upstream-arranged, first adjustment segment. The adhesive-backing apparatus is divided into at least two additional adjustment segments that successively follow each other in a transport direction of the book blocks. Each adjustment segment includes a separate drive and a number of book block positions which is the same for each adjustment segment or differs maximally by three book block positions.

Abstract: A glue application roller for use in a gluing assembly equipped with at least one scooping roller includes a glue roller body that is provided with a central hole to receive a drive shaft. The glue roller body has at least two parts including a base and an outer ring. The base is operatively connected to the drive shaft by a non-positive fit. The outer ring is configured with at least one cavity. The base and the outer ring are coupled to each other non-positively via at least one first means. On at least one side of the glue roller body, there are second means that ensure that compressed air and/or another gaseous or liquid medium is fed into or discharged from the cavity so as to effectuate a change in a circumferential contour of the cavity.

Abstract: A method for applying portions of a backlining material to a back of a book block includes transporting the book block in a conveying direction in a book production line. The back of the book block is provided with an adhesive, wherein the book block is initially provided with the adhesive over an entire back length of the book block in a single application process. Then, the portions of the backlining material are applied in succession to the back of the book block, wherein at least a first portion of the backlining material is applied by a first conveying device and subsequently at least a second portion of the backlining material is applied by a second conveying device to the back of the book block such that at least one of the portions overlaps another one of the portions.

Abstract: A new cultivar of Vinca plant named ‘Rainer’ that is characterized by young leaves that are variegated yellow-green in color, a compact habit and violet-blue colored flowers.

Abstract: A shaping tool for a device for rounding a spine region and for shaping a folding region of a lying outstretched book cover, the folding region being adjacent on either side of the spine region, in accordance with a shape of a spine of a book block, which subsequently forms a book together with the book cover, includes a fixed, convex central shaping strip. Two convex outer shaping rails laterally adjoin the central shaping strip and are laterally adjustable according to a required rounding and width of the spine region of the book cover.

Abstract: An apparatus and a method for the preforming and rounding of a book block. A support strip is arranged at an adjustable loading height for accommodating a fore-edge of the book block to be rounded. A transport device transports the book block at the loading height toward the support strip. A preform press is adjustable in a vertical direction above the back of the book block and includes at least two preforming tools. A rounding device including two rounding rolls driven in opposite directions for rotation around parallel rotational axes clamps the book block between the two rounding rolls for rounding the book block. At least a first drive is connected to at least one of the preforming tools to displace at least one of the preforming tools in a longitudinal direction extending parallel to the rotational axes to change a spacing between the preforming tools in the longitudinal direction.
